1. Fusion and the Proton Proton Chain

Fusion is when lighter nuclei join together to make heavier elements, in the process some of their mass turns to energy and this is why our Sun shines. But it is not as simple as four hydrogen nuclei (protons) colliding at the same place at the same time. This video shows the proton-proton chain in a bit more detail. Now if only we could get this to work on Earth...
